Mangaluru: Arecanut found non-carcinogenic, Research by Nitte University confirms

A significant finding from Nitte University’s researchers has brought relief to arecanut farmers: arecanut itself is not carcinogenic. Instead, it appears to neutralize cancer cells, according to a recent study.

This discovery challenges the earlier classification of arecanut as carcinogenic by the World Health Organization (WHO), which caused widespread concern among arecanut growers. Critics argued that the classification was based on the association of arecanut with tobacco-based products like pan masala and gutkha, without conducting comprehensive research. The latest study by Nitte University experts highlights the distinction between arecanut in its natural form and its use in harmful combinations.

Background of the Research

Three years ago, an MoU was signed between Campco, the Arecanut Research and Development Foundation, and Nitte University to study the health impacts of arecanut. The research was conducted across four areas:

The effect of arecanut extract on zebrafish.
Its impact on fruit flies (Drosophila).
The influence of arecanut extract on cancer cells.
A scientific survey of arecanut chewers.
The studies in the first three areas have been completed, and findings are set to be published in international journals.

Key Findings

No Adverse Effects:

The research team, led by Prof. Idya Karunasagar, found no harmful effects of arecanut on health. The aqueous extract of arecanut was tested on fruit flies and zebrafish at various developmental stages. Both species exhibited no negative impacts.

Neutralizing Cancer Cells:

In a separate study, cancer cells were cultured in Petri dishes and treated with arecanut extract. The results showed that the extract inhibited the growth of cancer cells while leaving normal cells unaffected.

Support for Traditional Knowledge:

These findings align with traditional beliefs in India about the non-harmful nature of arecanut.

Ongoing Research

The fourth phase of the study focuses on people who chew only arecanut without combining it with tobacco. The Community Dental Health Department at Nitte University is conducting the survey, which requires more time due to the need for extensive sampling.

Expert Opinions

Keshav Bhat from the Arecanut Research and Development Foundation stated that earlier studies had already suggested that arecanut is not carcinogenic. The Nitte University report adds further weight to this conclusion.

Campco President Kishore Kumar Kodgi remarked, “The findings from Nitte University have reassured arecanut growers. Comprehensive studies led by the central government are still awaited, but this research strongly supports arecanut’s safety.”
